How to stop an iLogic loop with the keyboard

[Anonymous]

Hi,

Is it possible to stop an infinite loop when running an iLogic rule?

Thanks,

I wonder if this will be added in 2020....

@arron.craig, do you have Visual Studio installed? If so you can use it to attach to the Inventor 2019 process and then "Break All".  This will most likely jump right to your rule code in Visual Studio. You might be able to break out of the loop that's currently running. And if you can't break out, you can at least step though the statements in the loop to find out why it's stuck.

I figured it out. The vb file is stored in

appdata\Local\Temp\iLogic Rules

if its not there, go back to \Temp and find the most recent .out (moldDesignFileHandler) file and open it in visual studio. this gave me the location where all of my inventor vb files were saved.

this just saved me a days worth of work

hope this helps

Still waiting in 2021..... 10 years is a long time to wait.  I hope the OP shut down his computer by now.

I am in 2023, This feature was added?

@Leonardo_Czuy , in Inventor 2023 and 2024 there is no easy way to stop an infinite loop. However, if you have Visual Studio you can attach to the Inventor process and debug to try to find out why the rule is stuck in a loop.

If you know that a loop might run too long (or forever) in some situations, you can add code to check if a key is down and exit the loop in that case. See the attached rule for a sample. With that Keyboard class in your rule, you would add checking code such as the following in each loop:

ThisApplication.UserInterfaceManager.DoEvents
Dim keyDown = Keyboard.IsKeyDown(Keys.ShiftKey)
If keyDown Then
	Logger.Debug("shift key down = {0}. Exiting loop.", keyDown)
	Exit For ' use Exit Do for Do loops, or Exit While for While loops
End If

iLogic debug is available since 2019 with VS:

Just tested with VS2022 Community on IV2023.

Any progress on this?
